The maximum KE of the ejected electrons, therefore, increases with increasing light frequency and is independent of the light intensity, as observed experimentally. However, the number of photons striking the metal surface increases linearly with the light intensity.
Increasing the light intensity (photon energy per second per unit area) increases the rate at which electrons leave the metal, and the electrons have more kinetic energy. Changing the frequency of the light while keeping the intensity constant should not change the rate of electron emission.
